Advice?

My boyfriend told me to abort the baby (I'm 12w) because we were arguing about him lying and talking to his ex. I told him calmly if he could please leave, he said no. He then said "shut the fuck up before I make you have a miscarriage" after he said that I got extremely upset and went downstairs. My brother was over and he asked what was wrong and I told him. He was so pissed, but didn't get involved per my request. My brother told me that I need to get him out if I want him out, so I went back upstairs and asked him to leave again. My boyfriend said he would when he was good and ready too. I started to pack up his things and he grabbed me by my shirt and yanked me to him and then pushed me unto the bed. Grabbed his things and left and said that he never wanted a baby with me and that he hates me. He also stated that he doesn't want anything to do with the baby nor I. I can't help but feel sorry for myself. I never wanted to be a parent out of fear of being a single mom. I was raised by my mom alone and I turned out OK besides the unhealthy relationships I've held in my life. This argument was not something that just happened tension has been building up for the past month. Our two year relationship has been shitty.

Is there any single moms out there that can reassure me that I can do it on my own?

Is there any soon to be moms who will be doing it alone on here? What makes you go along with your day knowing that you'll do it alone?

I'm 21, bachelors degree, with a good salary paying job. I don't need him but I don't want to do it alone. I just think I'm a paradox because I'm a caseworker telling my clients not to degrade themselves or let anyone else do it yet I let a man do it to me for a long time.

Is it normal to cry every time I think about him? Miss him? I am lost. I don't know what to do anymore.

I have a support system that consists of family, friends, and coworkers. However, I'm only utilizing my family and one close friend at this time but I am not sure if I am making the right decision of leaving him.

Sorry that it is so long. Any advice is greatly appreciated. Thank you all who comments.
